Loco-check presents a useful tool to determine health-related quality of life in elderly people with lumbar spinal stenosis

Abstract

BackgroundLocomotive syndrome (LS) is a condition of decreased mobility caused by disorders of the locomotive organs. Lumbar spinal stenosis (LSS) is an LS disorder. The loco-check is a simple questionnaire comprising seven questions that can detect LS. The differences between the health-related quality of life (HRQoL) of elderly persons without LSS and those with LSS remain unclear. The primary aim of this study was to clarify these differences using the European quality of life (EuroQoL) scale. The secondary aim was to clarify the differences between the groups based on loco-check questionnaire responses. MethodsWe recruited patients aged ≥65 years. Our age- and sex-matched case/control cohorts included 28 elderly patients with LSS and 28 without LSS. The study participants were evaluated by the number of “yes” answers on the loco-check, the HRQoL using EuroQoL-5 dimension (EQ-5D) utility values, and the EuroQoL-visual analog scale (EQ-VAS). We compared differences between patients with and without LSS regarding HRQoL using EQ-5D utility values, EQ-VAS scores, the number of “yes” answers on the loco-check, and details of the loco-check. ResultsPatients with LSS had significantly lower EQ-5D utility values (p < 0.01) and more “yes” answers on the loco-check (p < 0.01) than those without LSS. There were no significant differences in EQ-VAS scores between groups (p = 0.09). There were statistically significant differences between groups in all questions except two: You often trip up or slip around the house and You can't make it across the road before the light turns red. ConclusionsElderly patients with LSS had lower EQ-5D utility values and more “yes” answers on the loco-check than elderly persons without LSS. Our results may clarify differentiating features of elderly patients with and without LSS.
